Figure 5.

The modules with a strong correlation with kidney malondialdehyde concentrations (MDA), a lipid peroxidation marker. The interactions among different nodes (OTUs) within a module were shown: solid line: positive correlation; dashed line: negative correlation. The color of each node (OTU) indicated the phylum this OTU was assigned. Modules M27 and N09 were identified from the groups M and N, respectively. The group N: healthy mice supplemented with PBS; The group M: mice subjected to exhaustive exercise stress supplemented with PBS. The detailed annotation of each OTU node can be found in Table S3.
